Maximus Unbreakable NiTi Dual-Band HT Antenna (BNC, 2m/70cm)
Maximus is Iron Spear’s BNC dual-band HT antenna for 2m/70cm — a ready nitinol/NiTi handheld whip for operators who want flexible, daily-carry performance without building one. “Unbreakable” here means NiTi spring-back / daily-carry resilience, not mil-spec or literal indestructibility. Handmade in-house in Idaho. Not an HF portable monopole. If you are comparing well-known NiTi sticks (including Signal Stick–style options), Maximus is our dual-band BNC answer in a lineup that also includes Guardian, Minimus, and Maximus Mobile. Browse the ham radio antennas collection and confirm connectors with the adapter guide: Handheld Radio Adapter Guide.
Stop letting flimsy antennas compromise your signal. The Maximus is handcrafted from nearly indestructible Nickel Titanium for crystal-clear dual-band (2m/70cm) communication, even in the harshest conditions. Bend it, twist it, it always returns to form. Backed by a Lifetime Warranty.
"WARNING: High SWR can damage your radio. Always tune and verify your antenna system before transmitting."

FAQ
What bands is Maximus for?

The BEST Antenna !

Awesome unit! We have used these on multiple operations in austere conditions and they have held up very well
So far it appears to be well-made and I am getting good reception. Time will tell on the durability.
Nice and flexible with integrated BNC connector - who could ask for more?
I'm honestly a bit disappointed in the Iron Spear Maximus antenna. The first issue is that it's shipped folded, pretty tight. So now, out of the bag, my antenna has got a permanent partial bend. It's not a huge deal, but other flexible antennas have arrived to the house, straight, and it's on me to mess them up. The BNC adapter is overly snug. I've had a hard time getting it off some radios (not others, depends on the female side of the bnc I suppose, but it's been snug everywhere).
The look and feel is nice though. I like the paracord-style wrapping. I think adding the frequency range the radio covers to the label is a very nice touch. Transmission and reception seem quite good. I tested the antenna with a couple of competitors and it's at least as good, if not better. So, the most important part of an antenna, well, that's here and in place.
Maybe changing how it gets shipped, winding it a bit less tightly maybe, I'm not sure. And that BNC is too much of a struggle. I do swap antennas (sometimes using dual band, sometimes mono-band, depending, it's why I went with BNC).
Great potential here, but a bit more polish needed.
